Understanding the Answer
Let's break down why this is correct
Answer
Empirical Risk Minimization chooses a hypothesis that minimizes training error, but if the hypothesis class is too simple—such as a linear model for data that follows a curved pattern—then the model will be unable to capture the underlying relationships, producing high bias. Because the model cannot fit the training data well, its training error remains large and its generalization error also stays high. This situation is classic underfitting, where the model is too restrictive and fails to learn the true pattern. For example, fitting a straight line to points that actually follow a quadratic curve will leave large residuals both on the training set and on new data.
Detailed Explanation
A model that is overly simplistic has too few parameters to learn the patterns in the data. Other options are incorrect because The misconception is that a very complex model will always underfit; The misconception is that a perfect fit guarantees good performance.
